Not any harder then installing a wired computer. With a wired computer you still have to put the magnet on the spoke and a sending unit on the fork then run the wire and computer up to the handlebar (I don't like using zip ties or tape so I just twisted the wire around the front brake cable-allowing enough slack so the wheel will turn or you'll pull the wire out of the computer!). With a wireless, you put the magnet on the wheel, place the sending unit on the fork, then just mount the computer and your good to go. The only technical part (if you call this technical), with the wireless is to make sure the sending unit has it's internal antenna pointing up towards the computer, and that the sending unit is not too far from the computer so as not to recieve a signal, which in every case I've seen that was never an issue. So I actually think the wireless is easier to set up because I don't have to fool with a wire.
